FURNACE FOR DEOXIDIZING IRON ORE-S.

SPECIFICATION forming part of Letters Patent No. 260,539, dated July 4, 1882.

Application filed October 11, 1881. (No model.)

To all whom itmay concern:

Beit known that I, ISRAEL D. CONDIT, Jr., of Millburn, in the county of Essex and vState of New Jersey, have invented certain useful Improvements in Furnaces for Deoxidizing Iron Ores, of which the following is a full,clear, and exact description. i

Reference is to be had to the accompanying drawings, forming part of this specificatiornin which similar letters of reference indicate corresponding parts in both the gures.

Figure 1, Sheet 1, is a perspective view of my improvement, parts being removed. Fig. 2, Sheet 2, is a sectional end elevation of a double furnace,the left-hand part being taken through a retort and the right-hand part being taken through a ilue between two retorts.

The object of this invention is to improve the construction of the furnaces for which Letters Patent Nos. 128,993 and 145,471 were granted, respectively, July 16, 1872, and De cember'i), 1873, Joel Wilson inventor, in such a manner as to distribute the heat more equally and eliminate the oxygen more uniformly in less time and at a less cost than is possible with the construction heretofore used.

The invention consists in a furnace for deoxdizing ores constructed with ya heat-distributing chamber and vertical flues located directly beneath the retorts and leading into the flues surrounding the retorts, as will be hereinafter fully described.

I build the furnaces of tire-brick, in rectangular form, and prefer to build them double, the -two sets being set back to back against a division-wall.

A is a flue, through which the products of a combustion from a forge-lire, a puddling-fur- .from it lues C extend' upward to the crossflues D beneath the bottoms of the retorts H. In the flues D the products of combustion divide, partpassing up through the flues F at the y front sides of the retorts H and part passing up through the ilues G at the rear sides of the said retorts. The products of combustionfrom the flues F and G meet in the space, chamber, or flue K, above the' retorts H, and pass down through the iiues I between the said retorts H into the Vdischarge-flue J, from which, at any desired point, they can be led to the chimney. With this construction the retorts H will be heated upon all sides, so that all parts of the ore within the said retorts will be heated equally and the ore will be deoxidized evenly, the oxygen being eliminated in less time and at a much less cost than when a furnace constructed in the ordinary manner is used.

The ore to be deoxidized is introduced into the retorts H through openings L in the tops of the said retorts, and the deoxidized ore is withdrawn through the discharge-dues M,

which lead down from openings N in the bottoms of the said retorts H, as indicated in Fig. 2.

Having thus fully described myinvention,

I claim as new and desire to secure by Letters Patent- 1. In afurnace for deoxidizing ores, the combination, with the inlet-tine A, the retorts H, and the transverse fines I), arranged beneathV the retorts and communicating with said inlet-line, of the iiues F G I andthe chambers K, substantially as shown and described, whereby the heat is distributed equally all around the retorts, as setforth.

2. YIn a furnace for deoxidizing ores, the combination, with the heat-inlet iiue A and the iues -D F G K I, surrounding the retorts H, of the heat-distributing chamber B and the vertical lues (l, locatedl directly beneath the retorts, substantiallynas herein shown and described,whereby the heat is distributed equall all around the retorts, as set forth. l

The above specification of my invention signed by me this 7th day of October, 1881.
